In standard serial I/O mode, the user ROM area can be rewritten while the MCU is mounted on-board by using a
serial programmer which is suitable for the MCU.
Standard serial I/O mode is used to connect with a serial programmer using a special clock asynchronous serial I/O.
There are three standard serial I/O modes:
This MCU uses standard serial I/O mode 2 and standard serial I/O mode 3.
Refer to Appendix 2. Connection Examples between Serial Writer and On-Chip Debugging Emulator.
Contact the manufacturer of your serial programmer for additional information. Refer to the user’s manual of your
serial programmer for details on how to use it.
Table 18.7 lists the Pin Functions (Flash Memory Standard Serial I/O Mode 2), Table 18.8 lists the Pin Functions
(Flash Memory Standard Serial I/O Mode 3). Figure 18.17 shows Pin Connections for Standard Serial I/O Mode 3.
After processing the pins shown in Table 18.8 and rewriting the flash memory using a programmer, apply “H” to
the MODE pin and reset the hardware to run a program in the flash memory in single-chip mode.

The ID code check function determines whether the ID codes sent from the serial programmer and those written
in the flash memory match (refer to 18.3 Functions to Prevent Rewriting of Flash Memory).
Standard serial I/O mode 1 ................ Clock synchronous serial I/O used to connect with a serial programmer
Standard serial I/O mode 2 ................ Clock asynchronous serial I/O used to connect with a serial programmer
